So there was this little argument whether ants have bones or not. Then it was noted that even snakes don’t have bones… Was just trying to figure out animals who don’t have bones.
Wiki Answers says
Insects and spiders don’t have bones. Worms, snails and slugs don’t have bones.
And cool quiz says that snakes do have bones.
Snakes are full of bones, from their sectioned backbones, to which are attached from one to 145 pairs or ribs, to the ball and joint sockets, which attach the many sections of backbone together, and allow them to contort themselves like pretzels.
An invertebrate is an animal without backbones. and 95% of species in the world are invertebrates.
